Clipboard History Switcher is actually more like a Clipboard Manager. Whenever you copy something from any app, the Keyboard Maestro Engine saves a copy of the System Clipboard at that time to the Clipboard History file.
The Clipboard History Switcher (CHS) allows you to:
A typical display of the Clipboard History Switcher looks like this:
The Clipboard History Switcher is displayed using the Activate Clipboard History Switcher Action. You can find a Macro that uses this Action in the Switcher Group Macro Group (which comes installed with Keyboard Maestro).
Most of these Toolbar buttons operate on the selected Clipboard. There are currently no keyboard shortcuts for these tools.
This menu is available by either clicking on the Gear ⚙ Button on a Clipboard, or by right-clicking anywhere on a Clipboard.
Most of the these menu items are designed to operate on one or more Clipboards, and produce a new Clipboard, which can later be pasted if desired.
* Processing by Your Custom Macros
Select two or more Clipboards (using standard macOS multiselection), and then you can:
* Switch Between Normal Clipboard History and Named Clipboard Switchers
Keyboard Maestro keeps a copy of everything you copy automatically each time you copy something. You can exclude certain applications (for example, badly behaved applications or applications that often have very large clipboards) using the Preferences > Excluded Preferences Panel in the Keyboard Maestro Editor app.

By default, Keyboard Maestro creates a Clipboard History Switcher macro in the “Switcher Group” Macro Group, triggered by Command-Control-Shift-V. You can disable the Macros by selecting them in the Macros window pane and clicking the ✓ button.
Keyboard Maestro also has many macros in the Macro Library, such as macros for Paste Plain Text (Command-Shift-V) and Paste Previous Clipboard (Command-Control-V).
